为TableView单元格添加自定义字体遇报错，求技术解决方案

Hey there, let's get that custom font working in your TableView cell and squash that compile error first!

First: Fix the Immediate Compile Error #

The syntax error you're hitting is super straightforward—you messed up the argument list for the UIFont initializer. Your code has an extra comma that doesn't belong:

cell.nameLabel.font = UIFont(name: "USIS 1949", size, 25)

That's invalid Swift syntax. The UIFont initializer only takes two parameters: the font name and the size. Fix it like this:

cell.nameLabel.font = UIFont(name: "USIS 1949", size: 25)

Next: Ensure the Font is Properly Imported & Configured #

Even after fixing the syntax, the font might still not show up if you skipped critical setup steps. Let's walk through what you might have missed:

• Add the font file to your project correctly:
  Drag your .ttf/.otf font file into Xcode, and make sure you check the box for your app target in the "Add to targets" prompt. Double-verify by selecting the font file in Xcode and checking the target membership in the right sidebar.

• Update your Info.plist:
  Add the Fonts provided by application (raw key: UIAppFonts) array to your Info.plist. For each font, add a string entry with the exact filename (including the extension, e.g., USIS1949.ttf). Capitalization and spelling matter here—don't guess!

• Find the actual internal font name:
  This is the most common gotcha: font filenames often don't match the internal name iOS uses. For example, your file might be USIS1949.ttf but its real name is USIS-1949.

  To uncover the correct name, run this snippet once in your app (like in your view controller's viewDidLoad) and check the console:

  for family in UIFont.familyNames.sorted() {
      let fontNames = UIFont.fontNames(forFamilyName: family)
      print("Font Family: \(family) | Available Fonts: \(fontNames)")
  }
  

  Look for your font in the output, then use that exact string in your UIFont initializer.

Final Check: Make Sure No Code Overrides the Font #

Double-check your TableView cell setup:

• If you're using a storyboard/xib for the cell, ensure you haven't set a static font there that overrides your code-set font.
• Check if your cell's awakeFromNib() or layoutSubviews() methods reset the label's font behind the scenes.

Corrected Full Code Example #

Here's your code with the syntax fix and a reminder to use the correct font name:

let question = QuestionController.questionsList[questionIndex]
cell.nameLabel.text = question.answers?[indexPath.row]
cell.nameLabel.numberOfLines = 0
cell.nameLabel.lineBreakMode = .byWordWrapping
// Replace with the actual font name you found from the console output
cell.nameLabel.font = UIFont(name: "Actual-USIS-1949-Name", size: 25)
